Abstract

High Resolution Gamma-ray Spectroscopy (HRGS) and Total Absorption Gamma-ray Spectroscopy (TAGS) techniques of beta decay study and facilities for such techniques at VECC, Kolkata have been described. The preliminary results of the HRGS experiment performed at VECC to study the beta decay of 126 Sb, an important nucleus for the reactor decay heat estimation, are presented. The observation of a 928-keV gamma ray confirmed the 2703.6 keV state in 126 Te. The half-lives of both the beta-decaying states in 126 Sb could be uniquely measured in this work. The results are useful for future TAGS measurements of the 126 Sb beta decay.

Pretraining has recently greatly promoted the development of natural language processing (NLP)
We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
