The carbon ion-beam has emerged as a novel physical mutagen for creating genetic variability and crop improvement. In this study, seeds of high-yielding pyramided rice line MR219-PL-5 were exposed to ion beam irradiation at 10, 20, 40, 60, 80, 100 Gy. radiosensitivity test was conducted determine the optimum dose based on lethal 50% (LD50) using Sandwich Blotter Technique. biological responses ...

2014 The depolarization, broadening and shift constants of the 5 2P1/2 ~ 5 2S1/2 resonance line perturbed by rare gases are calculated in the semi-classical approximation when neglecting the excitation transfer to the 2P3/2 state in the energy range 100-1 000 K. Trajectory effects are discussed. The calculations have been performed with the interatomic potential recently published by Baylis [1]...
