for ( unsigned int i =0; i < myHist->GetNbinsX(); i++)

       {
          cout << myHist->GetBinContent(i);
          delta1 = new TH1F("BinContent", "BinContent",100,0,100);  //
<-- I think the problem is here
          delta1->Fill (myHist->GetBinContent(i));
        }

You can declare the histogram outside the loop, and if you want an empty histogram just do

myhist->Reset();
