We proposed a new mechanism of LENR: cooperative processes in whole system - nuclei+atoms+condensed matter can occur at smaller threshold energies then corresponding ones on free constituents. The cooperative processes can be induced and enhanced by low energy external fields. The excess heat is the emission of internal energy and transmutations at LENR are the result of redistribution inner energy of whole system.
The connection of synthesis of long-lived superheavy nuclei and existence of the island of stability with the choice of realistic nuclear potential is discussed: the behaviour of the average field of nuclei is an important element of nuclear models. It is also shown that it is just Dubna that possesses the priority both in the recent synthesis of a superheavy nucleus with charge Z=114 and in its theoretical prediction made 35 years ago. Possible sizes of the island of stability of superheavy nuclei are considered.

It is shown that it is just Dubna that possesses the priority both in the recent synthesis of a superheavy nucleus with charge Z = 114 (Flerov Laboratory of Nuclear Reactions, JINR) and in its theoretical prediction (Bogoliubov Laboratory of Theoretical Physics, JINR) made 33 years ago. Possible sizes of the island of stability of superheavy nuclei are discussed.
To take into account the 2p shell in calculating the wave functions for light nuclei in a realistic potential of finite depth, it is necessary to consider the problem of quasibound states. In this approach, which is used here to describe A = 13 nuclei, single-particle wave functions are represented as superpositions of eigenfunctions of the Sturm-Liouville problem. The nucleon wave function and binding energy in the 2p shell are calculated for the C-13 and N-13 nuclei. The asymptotic behavior of the nucleon wave function in this state is considered. The effect of meson-exchange currents and astrophysical applications are also discussed.
We describe how polarization-transfer data can be used to identify Jπ = 0−, 1−and 2− components of the ΔT = 1, ΔL = 1, ΔS = 1 isovector "spin-dipole" resonance seen in charge-exchange reactions at medium energies. Data for 40Ca(p,n) are compared with distorted-wave impulse approximation (DWIA) calculations with theory of finite Fermi systems (TFFS) wave functions.
The ground state of the 11Li nucleus is investigated by means of the hyperspherical harmonics method. The binding energy, RMS distances between constituents and inclusive momentum distributions are calculated together with 9Li-n and n-n momentum correlations.
The /sup 90/Zr(/sup 7/Li,/sup 7/Be)/sup 90/Y reaction as studied at /sup 7/Li ion energiesof 78 MeV in the angular range 10--28/degree/. At all angles, structure is seen inthe energy spectra that is associated with particle-hole excitations of the/sup 90/Y nucleus, with maxima at /ital E//sub /ital x//=1.7 and 4.6 MeV. Theexperimental results are analyzed by the distorted-wave method with use oftransition densities for states found on the basis of the theory of finite Fermisystems. It is shown that the hard part of the energy spectrum of /sup 7/Be isexplained by the one-step charge-exchange mechanism. With increased/ital E//sub /ital x// the role of multistep processes grows. According to ourcalculations, for excitation energies of /ital E//sub /ital x//0--3 MeV, theprincipal contribution is given by transitions with /ital L//sub /ital t//=1 and 3,while for /ital E//sub /ital x///gt/8 MeV, it is given by transitions with/ital L//sub /ital t//=4 and 6. In the region /ital E//sub /ital x//=3--7 MeV, the crosssection is governed in pratically equal measure by all the indicatedmultipolarities.
