As a successive work a modified D pair independent of the S pair treated in our previous papers is introduced to avoid the seniority mixing problem. The struct
A telescope system composed by a gas ionization chamber(IC)and an energy stopping detector made by the home-made CsI(T1)crystal has been successfully tested wit
