Excitation of nuclear collective states by heavy ions within the model of semimicroscopic optical potential

Abstract

The (semi)microscopic double-folding nucleusÄnucleus optical potentials are suggested for consideration of inelastic scattering with excitation of collective nuclear states by using the adiabatic approach and the elastic scattering amplitude in the high-energy approximation. The analytical expression for inelastic scattering amplitude is obtained keeping theˇrst-order terms in the deformation parameter of a potential. Calculations of inelastic cross sections for the 17 O heavy ions scattered on different nuclei at about hundred MeV/nucleon are made, and the acceptable qualitative agreement with the experimental data is obtained without introducing free parameters. The prospect of the method for further applications is discussed."²Ö · ¸¸³μÉ·¥´¨Ö´¥Ê ¶·Ê£μ£μ · ¸¸¥Ö´¨Ö¸¢μ §¡Ê¦¤¥´¨¥³ ±μ²²¥±É¨¢´Ò̸μ¸ÉμÖ´¨°Ö¤¥· ¶·¥¤² -£ ¥É¸Ö¨¸ ¶μ²Ó §μ¢ ÉÓ ( ¶μ²Ê)³¨±·μ¸±μ ¶¨Î¥¸±¨°Ö¤·μ-Ö¤¥·´Ò°μ ¶É¨Î¥¸±¨° ¶μÉ¥´Í¨ ², ¤¨ ¡ ɨΥ¸±¨° ¶ μ¤Ì줨 ³ ¶²¨ÉÊ¤Ê Ê ¶·Ê£μ£μ · ¸¸¥Ö´¨Ö ¢ ¢Ò¸μ±μÔ´¥·£¥É¨Î¥¸±μ³ ¶·¨¡²¨¦¥´¨¨. μ²ÊÎ¥´μ ´ ²¨É¨-Î¥¸±μ¥ ¢Ò· ¦¥´¨¥ ¤²Ö ³ ¶²¨ÉʤҴ¥Ê ¶·Ê£μ£μ · ¸¸¥Ö´¨Ö, £¤¥ ʤ¥·¦¨¢ ÕÉ¸Ö Î²¥´Ò ¶¥·¢μ£μ ¶μ·Ö¤± ¢ · §²μ¦¥´¨¨ ¶μÉ¥´Í¨ ² ¶μ ¶ · ³¥É·Ê ¤¥Ëμ·³ ͨ¨. ‚Ò ¶μ²´¥´Ò · ¸Î¥ÉÒ´¥Ê ¶·Ê£¨Ì¸¥Î¥´¨°· ¸-¥Ö´¨Ö ÉÖ¦¥²Ǫ̀μ´μ¢ 17 O · §´Ò³¨Ö¤· ³¨ ¶·¨Ô´¥·£¨ÖÌ μ±μ²μ 100 OEÔ‚/´Ê±²μ´,¨ ¶μ²ÊÎ¥´μ Ê¤μ¢²¥É¢μ·¨É¥²Ó´μ¥¸μ£² ¸¨¥¸Ô±¸ ¶¥·¨³¥´É ²Ó´Ò³¨¤ ´´Ò³¨¡¥ § ¢¢¥¤¥´¨Ö¸¢μ¡μ¤´ÒÌ ¶ · ³¥É·μ¢. ¡¸Ê¦¤ ÕÉ¸Ö ¢μ §³μ¦´μ¸É¨ ¶·¥¤²μ¦¥´´μ£μ ¶μ¤Ìμ¤ ¤²Ö ¤ ²Ó´¥°Ï¨Ì ¶·¨²μ¦¥´¨°.
