[en] The prompt gamma-ray data of thermal-neutron captures for nuclear mass number A=26-35 had been evaluated and published in 'ATOMIC DATA AND NUCLEAR DATA TABLES, 26, 511 (1981)'. Since that time the many experimental data of the thermal-neutron captures have been measured and published. The update of the evaluated prompt gamma-ray data is very necessary for use in PGAA of high-resolution analytical prompt gamma-ray spectroscopy. Besides, the evaluation is also very needed in the Evaluated Nuclear Structure Data File, ENSDF, because there are no prompt gamma-ray data in ENSDF. The levels, prompt gamma-rays and decay schemes of thermal-neutron captures for nuclides (26Mg, 27AI, 28Si, 29Si, 30Si, 31P, 32S, 33S, 34S, and 35CI) with nuclear mass number A=26-35 have been evaluated on the basis of all experimental data. The normalization factors, from which absolute prompt gamma-ray intensity can be obtained, and necessary comments are given in the text. The ENSDF format has been adopted in this evaluation. The physical check (intensity balance and energy balance) of evaluated thermal-neutron capture data has been done. The evaluated data have been put into Evaluated Nuclear Structure Data File, ENSDF. This evaluation may be considered as an update of the prompt gamma-ray from thermal-neutron capture data tables as published in 'ATOMIC DATA AND NUCLEAR DATA TABLES, 26, 511 (1981)'. (author)
