| Zusammenfassung: | The investigation of the distribution of the fusion-barrier height by heavy-ion collisions requires thin self-supporting targets. To increase the accuracy of the measurement the thickness and homogeneity has to be known as precisely as possible. We prepared the self-supporting nickel foils out of the isotopes super(58Ni, ) super(6)0Ni and super(61Ni. The resulting targets were between 75 and 105 mu g/cm) super(@) super(2) thick. The foils were produced on copper backing by electron-beam gun evaporation and by extracted ion-beam sputtering, both in high vacuum. To obtain self-supporting nickel foils the copper was removed by etching. We will discuss and compare both methods. |
